Hey, thanks for the report. Here are a few steps to narrow down the cause:

1. Check extensions  
Run this from Terminal:

```auto
cursor --disable-extensions

```

If the crashes stop, re-enable extensions one by one to find the one causing it.

1. Reset Cursor data  
This helped many users with the same error:

```bash
cd ~/Library/"Application Support"
mv Cursor CursorBackup

```

Then restart Cursor. Your settings will be reset, but the backup will stay.

1. Disable GPU acceleration

```auto
cursor --disable-gpu

```

1. Network  
If you’re using a VPN or a corporate proxy, open the app settings `CMD + ,`, search for “HTTP/2”, and enable “Disable HTTP/2”.

Also worth noting: you’re on macOS 12.7.4 (Monterey) on Intel, which is an older platform. Newer Electron and Chromium versions may be less stable on it.

If none of the above helps, please share:

- logs from Help \> Open Logs Folder \> `main.log` (around the time of the crash)
- whether you’re using a VPN or proxy
